unified tooltips as dictionary (#8)

## Changes
- From one variable for each tooltip to dictionary
- Should not break the game.

## How to test
- Run game
- In `cocina_delante` every tooltip yould appear as always.
- The rest of the rooms/items appear without tooltip.

## Side effects
- `set_tooltip` ESC command doesn't work untill `tooltip` is set to the in the new way. It changes the tooltip to every object without the new tooltip.
- Should be gone when we update every object.
